Answer :
The given statement "Jamil's teacher gives partial points for math questions that are worked correctly except for a calculation error. Jamil's total score on his last homework page was 99.3. Jamil's score is based on a discrete scoring system" is true, because (Jamil's score is based on a discrete scoring system.)
In a discrete scoring system, partial points can be awarded for specific tasks or steps completed correctly, even if the final answer is incorrect due to a calculation error. Jamil's score is based on a discrete scoring system. In a discrete scoring system, partial points can be awarded for specific tasks or steps completed correctly, even if the final answer is incorrect due to a calculation error.
This approach encourages students to demonstrate their understanding of the problem-solving process and rewards them for correct methodologies, rather than only focusing on the final answer.
In Jamil's case, his teacher follows this system and awards partial points for math questions that are worked correctly except for calculation errors. As a result, Jamil received a total score of 99.3 on his last homework page. This score reflects his performance across multiple questions, and the decimal value indicates that he received partial points on some of these questions.
In summary, Jamil's score is based on a discrete scoring system that emphasizes the importance of understanding the problem-solving process and awards partial points for correct work despite calculation errors. This system allows students to be recognized for their effort and knowledge, even if they make minor mistakes along the way.

The probability of passing a 10-question true-false quiz with a grade of at least 70 percent by guessing, one would calculate the sum of probabilities of answering exactly 7, 8, 9, or 10 questions correctly using the binomial probability formula. However, the exact calculations are not provided here and should be carried out by the student.
At hand involves determining the probability of a student passing a true-false quiz with at least a 70 percent grade by randomly guessing on each question. A true-false quiz presents only two possible outcomes for each question, making the chance of getting any single question correct 1/2 or 50%. To pass with at least a 70 percent grade on a 10-question quiz, the student must answer at least 7 questions correctly.
The calculation of this probability can be done using the binomial probability formula, which expresses the probability of achieving exactly k successes in n independent Bernoulli trials with success probability p. In this scenario, getting a question correct is the 'success', and we're looking for the sum of probabilities of getting at least 7 questions right out of 10. The formula is P(X = k) = (n choose k) * p^k * (1-p)^(n-k), where 'n choose k' is the binomial coefficient.
The addition of probabilities for getting exactly 7, 8, 9, or 10 questions correct will give the total probability that the student passes the quiz with at least a 70 percent grade. However, as a tutor without the ability to conduct the actual calculation in this response, it is recommended that the student perform this calculation using a binomial distribution calculator or by calculating each binomial probability and summing them up to find the final answer.
